The work of preparing International standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee.

7 International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical International standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International STANDARD requires approval by at least 75 % of the member bodies casting a STANDARD ISO 377 was prepared by Technical Committee ISO/TC 17, Steel, Subcommittee SC 20, General technical delivery conditions, sampling and mechanical testing second edition of ISO 377 cancels and replaces ISO 377-1:1989, which has been technically A forms an integral part of this International : Steels, iron and steel products, sampling, sampling location, samples, specimen preparation, mechanical.

8 1997 BSI 09-199911 ScopeThis International STANDARD specifies requirements for the identification, location and preparation of samples and test pieces intended for mechanical tests on steel sections, bars, rod, flat products and tubular products as defined in ISO 6929. If agreed in the order this STANDARD may also apply to other metallic products. It does not apply to non-destructive samples and test pieces are for use in tests which are carried out in conformity with the methods specified in the product or material STANDARD or, in the absence of this, in the test the requirements of the order or product STANDARD differ from those given in this International STANDARD , then the requirements of the order or product STANDARD Normative referencesThe following standards contain provisions which, through reference in this text, constitute provisions of this International STANDARD .

9 At the time of publication, the editions indicated were valid. All standards are subject to revision, and parties to agreements based on this International STANDARD are encouraged to investigate the possibility of applying the most recent editions of the standards indicated below. Members of IEC and ISO maintain registers of currently valid International 3785: , Metallic materials Designation of test piece axes1). ISO 6929:1987, Steel products Definitions and classification. 3 DefinitionsFor the purposes of this International STANDARD , the definitions given in ISO 6929 and the following test unitnumber of pieces or the tonnage of products to be accepted or rejected together, on the basis of the tests to be carried out on sample products in accordance with the requirements of the product STANDARD or order (See Figure 1.
